The Catholic bishop of Madison, Wisconsin, has banned employees with a local “spirituality center,” including two nuns, from speaking in his diocese over concerns that they are misrepresenting the Catholic faith and preaching the New Age religion.

Bishop Robert Morlino is well known to pro-life and pro-family activists for his strong defense of the Roman Catholic Church’s teachings, particularly on life and family. He has earned praise from Catholics in the past for cracking down on dissent in his diocese.

A memo from Msgr. James Bartylla, the vicar general of the diocese of Madison, explains that staff from the Wisdom’s Well Interfaith Spirituality Center are no longer permitted “to preach, catechize, lead spiritual or prayer instructions or exercises, or to provide spiritual direction or guidance” at any Catholic institutions in the diocese.

The center is also banned from distributing any of its materials or advertising in the diocese.
